What is Astaxanthin powder?
Astaxanthin powder is a red-orange carotenoid pigment , and it mainly from Haematococcus pluvialis, and also exist in marine organisms like krill, salmon, and crustaceans. Its molecular structure (C₄₀H₅₂O₄) features hydroxyl and ketone groups, and it have a outstanding clearn ability for free-radical. And regular it would be produced by powder . and the concentrations of 2–3% for supplements and cosmetics, it different from synthetic variants, natural algae-derived asaxanthin exhibits superior bioavailability and efficacy.

What are the benefits of astaxanthin powder?
As a Antioxidant, Astaxanthin Powder is have a strong ability and function .
And Neutralizes free radicals 550× more effectively than vitamin E and 10× better than β-carotene25. Its unique ability to span cell membranes protects both inner and outer lipid layers from oxidative damage across organs.
Anti-Inflammatory & Immune Modulation: Reduces key inflammation markers (e.g., CRP) and enhances immune cell activity, elevating protective enzymes like superoxide dismutase (SOD).
Organ-Specific Protection: Crosses the blood-brain barrier to support neuronal health, inhibits diabetic kidney damage, and improves cardiovascular lipid profiles by reducing LDL oxidation.
Skin and Vision Defense: Shields skin from UV-induced photoaging and wrinkles, while protecting retinal cells against macular degeneration.
